OVERHAULING OF MAIN ENGINE MAN 7S60MC

Our diesel engineers “in action”, on board, during overhauling of main engine. All cylinder covers, pistons, piston rods, exhaust valves and fuel pumps were removed and taken to the workshop for overhauling and repairs. Piston crowns were fully rebuilt and the combustion surface of cylinder covers was totally renewed by submerged arc welding. Piston rods were restored by Laser Cladding. All fuel pumps were fitted with new plungers made in our workshop. Fuel injectors were overhauled and adjusted. After boxing up the engine, sea trials carried out at full speed and engine was delivered in accordance to makers’ specification performance values.
